1.2.4 Reliability
1. Understanding an Overview of the System
The SPARC M12 is equipped with data protection, redundancy,
dynamic degradation, and other such high-reliability technologies.
Hardware as whole
■
Dual power feed
■
Redundant configuration of LAN
(by Oracle Solaris functions)
CPU
■
Dynamic degradation of CPU
(in units of cache ways or CPU cores)
■
●
RAS functions (ECC, parity, retry, etc.)
PCIe card
■
Redundant configuration
(when in multipath configuration)
*1 For an HDD, it is when a software RAID/hardware RAID is configured. For an SSD, it is when a software RAID is configured.
XSCF

■
Dynamic degradation of
memory (in units of pages)
■
Extended ECC
